To all whom it. may-concern:

Be it known that I, JOHN H. 0001;, a citizen of the United States,residing at the bore ou'gh ofBrooklyn, city of New York, county ofKings, and State of New York, have invented certain new and useful Imrovements in Wall-Anchors, of which the following is a specification.

My invention relates to improvements. in supports for universalapplication in the arts.

F or purposes of illustrating one use of my invention, I have shown itin the form of a wall support or socket, which may be secured to, orembodied in a wall for receiving and retaining bolts, screws or similarmembers of various sizes.

.The accompanying drawing is a perspective view of the device partsbeing broken away. Similar characters refer to similar parts throughoutthe several views.

A socket or body member 1 preferably though not necessarily formed solidand square in cross section and having annular projections 6 and 7formed thereon is preferably-provided with two wings or leaves 2 and 3each; having lugs 4 and 5 respectively to .enga'getthe reinforcing barsof a concrete or This socket member 1 has a longitudinal socket 8 formedtherein ex.- tending from front to rear with a contracted fixed screwthreaded member or neck section 9 at its forward end.

j within the longitudinal socket 8 I place one or more concentricinteriorly screw.

threaded movablemembers as nuts 10 and 1 1,tl1eaperturesinsaid movablemembers-1'0 and 11 are graduated, the movable member smaller screwaperture.

next adjoining the contracted fixed screw threaded member or neck 9 ofthe socket 8 having a screw threaded aperture smaller than that of theneck 9 and the next adjoin ing movable member 11 having a still Afterthe movable members or nuts are placed within the socket guard 12 overthe rear opening of the socket 8 to prevent the removal of the movable jmembers or nuts and also to prevent concrete or other foreign materialfrom entering the socket through this opening if the device is beingused in concrete construction.

. When my device is assembled as above described it. is inserted in thewall at any de- 8 I place a cover or sired point with thefront orsmaller end of the device preferably flush with the surface, and boltsof any desired diameter corresponding with the diameter of any of thescrew-threaded apertures of m T device may be inserted.

A bolt inserted in the screw threaded fixed member or neck of the'device'and of such size as to fit into those threads will not beinterfered with by the movable members 10 and 11, as their aperturesbeing of a smaller diameter than that of the" bolt, they will be asthebolt enters, and the same is true of each of the movable members, themember or nut receiving the bolt being drawn forward against the innerface of the contracted fixed member or neck 9 of the socket 8 and themovable member or nuts with smaller apertures bein pushed to the rear ofthe socket by the olt.

While Lhave shown only two movable members or nuts, as many movablemembers or nuts may be-used in the device as desired. The form of mydevice shown in the drawings is preferred as this prevents the devicefrom being pulled out of the wall in which it is embedded, and I alsoprefer to use the lugs 4 and 5 to engage reinforcing rods or barsusually provided in concrete walls, to more securely hold the socketmember. I also provide the wings 2 and 3 to prevent the device fromturning in the wall.

Vvhile I have described my invention in be distinctly understood that itis adapted for application with structures or articles formed of'masonry brick, metal, wood or any other material or any combination ofsuch materials; and "further it is adapted for universal application asa support with any article formed of any material. Furthermore thesocket member may be formed of 5 any contour though preferably it isformed .non-circular to prevent its turning in the structure in whicl'iit is embedded or fastened. ilt is to be also understood that both thewings and lugs maybe omitted or eitherof them as found convenient orexpedient and connection with a concrete structure, it is to P shed tothe back or rear of the socket I that the cover or guard may he likewiseomitted, or fastened, or cast inte ral with the socket or body member. Ipreferably form l the throat or fixed member integral with the 1 socket'niember but it may be otherwise seecured. The nuts may be of the formshown, though any other form of nuts or movable menu are may be used asdesired.

thus described my invention what I claim orly screw threaded aperturesof graduated sizes, and so arranged that the diameter of the aperture ofeach successive nut is larger than that of the nut behind it.-.

2. In a device of the character described, the combination of a socketmember provided with wings, and having a plurality of nuts havinapertures of graduated sizes, and so arrange that the diameter ofthe'aperture of each successive nut is the nut behind it.

3. In a device of the character described, the combination of a socketmember having wings which are provided with projecting lugs, and havin aplurality of nuts having apertures of graduated sizes, and s0 arranged tat the diameter of the aperture of each successive nut is larger thanthat of the nut behind it.

4. In a device of the character described the combination of a pluralityof concentrieally apertured bolt receiving members within a casing, thea ertures in the said bolt receiving members eing respectively arrangedso that the aperture of the bolt receiving members are graduated fromthe largest at the mouth of the socket member to't e smallest at therear thereof.

5. Ina su port, a body or socket member, a fixed mem er, secured to thebody member and provided with engaging surfaces and one or more movablemembers mounted in the body or socket member, said movable member ormembers being provided with graduated engaging surfaces. l

6. In a support, a body or socket member, a fixed apertured membersecured to the body member and provided with screw threads, one or morescrew threaded aperlarger than that of.

turcd movable members mounted in the body or socket member, theapertures of the fixed and movable member or members being graduated. v

7. In a wall socket, a body or socket member, a fixed member secured tothe body member and provided with faces and one. or more movable membersmounted in the body or socket member, said movable member or membersbeing provided with graduated engaging surfaces.

8. In a wall socket, a body or socket membar a fixed apertured membersecured to the body member and provided with screw threads, one or morescrew threaded apertured movable members mounted in the body or socketmember, the apertures of the fixed and movable member or members beinggraduated.

9. In a su port, a body .or socket member, a fixed mem er secured to thebody member and provided with engaging surfaces, one or more movablemembers mounted in the body or socket member, said movable member ormembers being provided with graduated ongaging surfaces and one or moreannular projections on the exterior of the body or socket member.

10. In a support, a body or socket menu her, a fixed apertured membersecured to tho body member and provided with screwthreads, one or morescrew threaded apertured movable members mounted in the body or socketmember, the apertures of the fixed and movable member or members beinggraduated and one or more wings and one or more annular projections onthe exterior of the body or socket member.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, this fifteenth day of April,1908.
